Specification of Letters Patent.

. Application filed December 13, 1909. Serial No. 532,930.

Patented June 13, 1911.

To all whom ii may concern:

Be it known that I, ISAAC SMYTH, a citi zen of the United States,residing at Chihis cago, county of Cook, and State of Illinois, haveinvented certain'new and useful Improvements in Automobiles, of whichthe following is a specification. w

My inventlon relates to improvements in automobiles and moreparticularly to a propelling means therefor, the object of the inventionbeing the production of a machine which shall be driven by the force ofgravity.

A further object of my invention is to provide adequate means wherebythe propelling means may be controlled for starting, braking, andstopping the vehicle, and automatic means for governing the speed of thesame.

Otherobjects will appear hereinafter.

With these. objects in view myinvention consists in the novelconstruction and arrangement of parts which will be hereinafter fullydescribed and particularly pointed out in the appended claims.

My invention will be best ufiderstood by reference to the accompanyingdrawings forming a part of this specification, and 1n which,

Figure 1 is proved automobile in its referred form and showing the neatexterna appearance there of, Fig. 21s also a side elevation, parts beingbroken away to expose the operating mechanism, Fig. 3 is a top plan viewof the automobile chassis, Figs. 4 and 5 are respectively a detail planview and side elevation showing the brake apparatus, and Figs. 6 and 7are respectively a detail plan View and side elevation showing theautomatic that when the drums 25 are rotated in one direction that theweights 31 will be elespeed governor or regulator of the vehicle.Referring now to the drawings 1 desl hates the automobile body and 2 thechassis (or running-gear carrying the same, the latter comprising the maor portion ofthe operating or controlling mechanism. While the lattermay be inadequate for long distance runs without excessive crankin it isparticularly adapted for short runs or city use or for use on the stageof theaters in certain plays in'which theautomobile figures as a factor.Toys also may be constructed on this principle. The usual wheels 3 andsupporting springs 4 and 4 are provided to support the chassis frame a2, and on the rear axles sprockets 5 are sea side elevation of myimvided and secured to one en said weights being adapted to move ver-'cured and driven by chains 6 in the usual" I manner. The driving shaft 7carries at the ends thereof the driving sprockets 8 as clearly shown inFigs. 1 and 2. The driving shaft? is driven by means of the chain 9which travels over the s rockets 9: and 10,

the latter being secure to the governor shaft 11. The sprocket 12 whichis secured 1 to the shaft 11 as shown connects with the sprocket 13 and,is driven thereby, the=latter sprocket being secured to the shaft .14.-

Sprocket 15 is secured to the shaft '14- and is driven by the chain 16which travels over,

and is driven by the sprocket 17, the latter being secured to the shaft18. The shaft 18 extends across the chassis frame 2" and is are drivenby the chains 20 which travel over the double sprockets 21 which aremounted on the studs 22 which extend in- Wardly from the outer membersof the frame 2'. The sprockets 21 are driven. by the chains 23 which inturn are driven by the sprockets 24 arranged at the outer end of therotatable drums 25. These drums'are provided with shafts 26 and 26'which are journaled in the frame 2 the. said shafts projecting outwardlyas shown in Fig. 3. The cords 27 are securedto the drums 25 and adaptedto wind about the same during rotation thereof, and said cords extendupwardly and pass over the pulleys 28 and 29 as clearly shown in Fig. 2.The pulleys 29 are suspended from the top of'the body by 7 means ofhangers 30. WeightsBl are protically on the inside of body 1.

From the foregoing description it is clear in the frame 2. By means ofthe connect-' ing rods 34.- the lower ends of the levers 32 areconnected to the res ective bell crank levers 34', one end of ,eac ofthe latter being provided with a brake shoe, which shoes impinge againstthe bevel faces 35 provided of the cords 27, I

thereon by means of the key-way 38, the :key

centrifugal force and thus tend to increase provided with a door way, adrum rotatably at the inner end of the drums 25. I Thus it will be seenthat when a hand lever 32 is moved rearwardly that a drum 25-will beretarded in its rotary movement by means of the friction between thebrake shoe and the bevel surface 35.

The speed governor comprises balls 36 which are mounted at the outerextremities of leaf springs 37, one of the latter being rigidly securedto the governor shaft 11". The other s ring is mounted in a groovedcollar 37' which is adapted to slide freely on the shaft ,11 andprevented from rotating 39 integral-with said collar projecting intosaid key-way. A disk 39. is provided on the collar 37 the periphery ofwhich is beveled and adapted to impinge'upon the bevel face 27 formed onthe inner end of each shaft 26. The balls 36 of the governor when at ahigh rotative speed fly outwardly by' the effect of the springs 37, andsince the collar 37 is connected with one of said springs the disk 39impinges upon the bevel face 27, the amountof pressure between said diskand said bevel face being determined by the centrifugal force of saidballs. The governor may be made so as to cause any desired frictionbetween the dog 39 and the bevel face 27', and hence the automobile mayrun at a predetermined speed. The outer ends of the shafts 26 and 26 aresquared and cranks 40 indicated by dotted lines are provided to cranksaid shafts.

Having described my invention what I' claim as new and desire to secureby Letters Patent is:

1. In an automobile, a chassis and a body mounted on said chassis, apulley suspended in said body adjacent the top and at one side of thedoor way, a cord wound about said drum and passing over said pulley, aweight on the free end ofsaid cord, a transve'rse shaft, gearinconnecting said transverse shaft and sai drum, a governor shaft, gearingconnecting said overnor shaft with saidfirst mentioned sha co-actingbeveled friction disks on said governor shaft and said drum, a. governoron said governor shaft for actuating the said disk on said shaft, adrive shaft, gearing connecting said governor shaft and said driveshaft, traction wheels and gearing connecting said drive shaft and saidtraction wheels, substantially as described? 2. In an automobile, achassis and a body provided with a door way, incombination with anoperators seat, a drum rotatably mounted on said chassis,a pulleysuspended in said body adjacent the top thereof and at one side of saiddoor way, a cord wound about said drum and passing over said pulley, aweight on the free end of said'cord, a transverse shaft, aringconnecting said transverse shaft an? shaft, caring connecting saidgovernor shaft with said first mentloned shaft, friction disks on saidgovernor shaft and said drum having co-acting beveled edges, a governoron said overnor shaft for actuating the disk on said shaft, a driveshaft, gearin connecting said governor shaft and said drive shaft,traction wheels, gearing connecting said drive shaft and said tractionwheels, a beveled face on said drum, a brake lever adjacent said seat, abell crank lever having a friction and on one of its arms adapted toengage the beveled face on said drum and a link connecting said brakelever and said bell crank lever, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ISAAC SMYTH.
